VINNAPAS® 418

VINNAPAS® 418 is an aqueous polymer dispersion based on vinyl acetate and ethylene. It is particularly suited in carpet binder applications where a soft hand is required. The dispersion combines moderately high solids content with a low viscosity — a combination that permits the addition of very high filler loadings, resulting in adhesive formulations with high solid contents.



特性

VINNAPAS® 418 may be used in applications where high filler loadings of calcium carbonate, aluminum trihydrate (ATH) or other fillers are required. The stabilization allows the dispersion to be compatible with acrylic dispersions and many styrene-butadiene lattices. VINNAPAS® 418 is not produced with any added organic solvents, plasticizers or formaldehyde donors.

免责声明

所提供之所有信息均基于我们当前所掌握的知识。尽管如此,我们不对其作任何担保、也不承担任何责任,并且保留在任何时候进行技术变更的权利。购买方应在预测试中对所提供之信息以及产品在既定应用中的适应性进行检查。任何时候都必须以合同条款与条件为准。此外,本免责申明还适用于与第三方权利有关之事宜,尤其是在德国境外。

General

VINNAPAS® 418 can be used in the precoat and secondary coatings that are applied in the production of tufted carpet backings. This includes outdoor grass (artificial turf). It can also be used in the production of woven carpets where a hand adjustment is required. VINNAPAS® 418 offers high adhesion strength, and good flexibility.

Special

VINNAPAS® 418 can be applied by a number of different application methods including foaming (direct coating), pan coating, saturation and spraying. VINNAPAS® 418 performs well on various fiber types including polypropylene, polyamide, cellulose, and polyester.

Processing

Foaming additives and dispersing agents can be added to VINNAPAS® 418 to improve foamability and filler acceptance. We recommend alkali-swellable poly(acrylic acid) derivatives. Products with neutral pH, e.g., those based on cellulose derivatives, poly(vinyl alcohol) or polyurethane, can also be considered. The compatibility and efficacy should be checked by conducting a storage test.

储存

When the dispersion is stored in tanks, proper storage conditions must be maintained. If stored in the original, unopened containers at cool (below 30 °C), but frost-free temperatures the product has a shelf life of 9 months from the date of manufacture. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Iron or galvanized-iron equipment and containers are not recommended because the dispersion is slightly acidic. Corrosion may result in discoloration of the dispersion or its blends when further processed. Therefore, the use of containers and equipment made of ceramics, rubberized or enameled materials, appropriately finished stainless steel, or plastic (e.g. rigid PVC, polyethylene or polyester resin) is recommended. As polymer dispersions may tend to superficial film formation, skins or lumps may form during storage or transportation. Filtration is therefore recommended prior to utilization of the product.

Preservation for Transport, Storage and further Processing

The product is adequately preserved during transportation and storage if kept in the original, unopened containers. However, if it is transferred to storage tanks, the dispersion should be protected against microbial attack by adding a suitable preservative package. To maintain proper storage conditions appropriate measures should also be taken to ensure cleanliness of the tanks and pipes. In a storage tank in which the product is not stirred, it is advisable to contact your biocide representative/supplier. Proper procedures must be set up in order to prevent microbial attack between necessary periodic tank cleaning and sanitization. These procedures will vary, since loading and unloading practices in each storage situation will differ slightly. Finished products manufactured from polymer dispersions usually also require preservation. The type and scope of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility with other components and the efficacy of the preservative should always be tested in the respective formulation. Preservative manufacturers will be able to advise you about the type and dosage of preservative required.
